Avid listeners of the alternative metal band known as Tool. Tool fans believe that, by listening to music with no concept of time signatures and pseudo-cryptic lyrics sang by a man known as Maynard Ivory James Keenan Wayans, it puts them on a higher intellectual and musical plateau than fans of non-"prog" bands. You can pick a Tool fan out of a crowd easily, by looking for a college student who speaks of issues which he has little to no understanding of, rants about conspiracy theories, is a half-hearted activist and constantly reeks of bong water. A Tool fan, as a rule, will never look presentable, wearing yesterday's hoodie and a baseball cap over his unwashed and shaggy hair.

You know Jeff? That annoying kid who shows up 30 minutes late to class every day with serious redeye and voices his stance on everything from abortion to extraterrestrialism without being asked? I hear he's a big Tool fan. Figures.
